HYDROCARBON-LAMP.

Application filed Match 25, 19.07. Serial No. 36 1,5218.

To all whom it may concern:

Be it known that I, 'WLLLIAM Tunas, a citizen of the United States, residing at Mil- Waukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Hydrocarbon- Lamps, of which the followin is a specification,

My invention relates to improvements in hydro-carbon lamps.

had to the accompanying drawings in which Figure 1 is a si( e view of a lamp embodying my invention with portions partially broken away to show the oil valve and the burner. Fig. 2 is an axial sectional view of the valve, generator, and a portion of the gas tube on a large scale. Fig. 3 is a detail plan view of the cleaning apparatus for the generator nozzle. Fig. 4 is across sectional view drawn on line a;:n of Fig. 2.

Like 7 arts are identified by thesa-me reference c aracters throughout the several views.

A reservoir 1. for hydro-carbon liquid is provided with a valved inlet 2 adapted to admit air under pressure to the reservoir,

from the lower portion of which a tubular liquid conveying standard 3 extends upwardly to a suitable valve casing {l rovided with a valve 5 having a stem 6 and andle 7 as shown. The valve controls the flow of liquid h dro-carbon to the generator tube 10 whic -is supported in a substantially horizontal position from the standard 3 bymeans of the valve casing 4 and a head piece 11. The enerator tube 10 is provided with heat absor ing exterior flanges 12 formed by screw threadin the tube. The tube contains suitable filtering material 13 such as wire gauze or asbestos wool. At its outer 'end the generator is provided with a nozzle 14 which may be cleaned from time tojtime by a, reci rocating needle 15 which extends through t e head piece and is provided with Specification of Letters Patent.

a yoke 16. This yoke 16 is looselyengaged by a crank pin 17 on a wheel l8, which is mounted orr .a shaft 19 and rotated by means of the'button handle 20. This needle therefore, has a definite field oi movement,

and cannot be manipulated in such aanannor as to injure the nozzle.

The head piece 11 is provided with a cylindrical tubular stud 21 which receives the, generator tube 10, and the outer end of the tube-1U is provided with .a collar 22. Both adapted to enter and fit snugly within the gas conveying tube 23 into which the generator telescopes.

lhe tube 23 is cutout on the collar 22 and the tubularstud 21 are its under side between the lcollar-22 and stud 21 to expose the generator tube through .an elongated opening 25, above :a portion .of which the tube is perforated at 26 to provide for a slow circulation of heated around the generator tubelO in the space'between it and the remaining upper portion-oil the wall of the tubeZS. The gas tube 23 extends outwardly from the generator and is bent downwardly and rear-wardl-y in goose neck form with the lower end elbowed and provided with a burner 27. i

A collar 30 is telescoped ulpon thegas tube 23 and an air receiving be 31 is provided with a hub 32 which also telescopes upon the gas tube. llheicolla-r 30 is threaded and provided with a nut 35 having va sonically tapered portion 36 adapted to enter the bell,

and regulate the admission of air as the nut is turned to adjust it to and from the bell. The gas tube 23 is apertured at 37 within the bell to admit theair to :the interior'of tube 23.

A sub-fire burner, comprising a tubular stem 40, flattened at its up er end and having slits 41, projects upward rsfrom the backwardly'extendin portion of the asftu-be, in i8 generator an 'is adapted the direction of t to permit the escape of ;a small quantity of gas .in .a thinflame elongated along the HHS of the generator. By holding a llghted inatch under the generator and-near the nozzle, sufficient heat will be absorbed by it to generate a small quantity of gas near the nozzle, which gas passes downwardly in the tube in sufficient quantity to ignite at'the sub-fire burner, whereupon a larger quantity of gas is generated with sufficient rapidity to permit the same match to be used in lighting the main burner 27.

With the above described construction,

the burner 27 with the shade or globe 42 are supported from the head iece through the gas conveying tube whicii is merely telescoped upon the generator.

I Having thus described my invention, what said projection and arranged in communication with the hydro carbon supply, a gas tube telescoped'over the generator tube and fitted to said projection and a burner supported by the gas tube substantially underneath the generator, said generator being horizontally disposed and ada ted to support the gas tube by. a detachable connection therewith, and said gas tube being out of contact with the central portion of the generator tube and apertured along its underside directly over the burner.

2. In a hydro-carbon lamp, the combina tion of a standard provided with a suitable head piece having a tubular projection and means for supplying liquid hydro-carbon thereto, a generator tube connected with and arranged to receive oil from said projection, and a gas tube telescoped over the burner and provided with an elongated opening on its under side, said gas tube being curved downwardly and backwardly and provided with a burner substantially underneath the generator, and said gas tube having its u per wall perforated above the burner and a ove said 0 ening.

3. n a hydro-carbon, lamp the combination with a suitable reservoir, of a horizontally projecting generator tube arranged in communication with the reservoir, a gas tube having one end portion telescoped over the generator tube and slidably supported at the respective ends of said generator tube, and a burner connected with the other end of the gas tube, said as tube being curved in oose neck form and arranged to support the burner underneath the generator, and said gas tube being provided with an opening in its underside exposing the generator directly over the burner.

4. In a hydro-carbon lamp, the combination with a suitable reservoir, of a horizontally projecting generator tube arranged to receive liquid hydro-carbon therefrom, a gas tube having one end portion telescoped over the generator and provided with an opening along its under side exposing the generator, and a burner supported by the gas tube underneath the exposed portion of the generator, said generator having a nozzle arranged to discharge into the gas tube, a cleaning needle adapted to enter the nozzle, and a crank mechanism operativcly connected with the needle, and adapted to move the same a predetermined distance into and out of the nozzle.

5. In a hydro-carbon lamp, the combination with a suitable reservoir, of a horizontally projecting generator tube arranged to rece ive liquid hydro-carbon therefrom, a

gas tube having one end portion telescopod over the generator and provided with an opening along its under side exposing the generator, and a burner supported by the gas tube underneath the generator, said gas tube having a collar telescoped thereon and threaded on its outer surface, an air bell having a tubular hub telescoped on the gas tube, and a valve nut'adjustably mounted on the collar and provided with a tapered.

portion adapted to enter the bell.

6. In a hydro-carbon lamp, the combination with a suitable reservoir, of a horizontally projecting generator tube arranged to receive liquid hydro-carbon therefrom, a gas tube having one end portion telescoped over the generator, and provided with an opening along its under side exposing the generator, and a burner supported by the gas tube underneath the generatorsaid gas tube being arranged to extend outwardly, downwardly and rearwardly from the generator in a goose neck curve, together with a sub-fire burnercomprisinga tube extending from the rearwardly extending portion of the gas tube toward the generator, with its upper end flattened and shtted to permit the escapeof a small quantity of gas distributed along the axis of the generator.

In testimony whereof I aflix my signature in the presence of two witnesses.

WILLIAM TUBES.
